Why Monitor Floor Plan Aging?

Inventory aging is the silent killer of dealership profitability. While a vehicle's sticker price remains the same, your net profit shrinks every day it sits on the lot due to floor plan interest, insurance, and maintenance.

Most dealers focus on the "Front-End Gross," but the "Net Profit" is what truly matters. By tracking aging costs, you can make smarter decisions on when to drop the price or send a unit to auction.

  • Identify units that are no longer profitable.
  • Calculate break-even points for price drops.
  • Motivate sales teams to move aged inventory.
  • Lower your overall interest expense.
